The effect that Brindley discovered, established the fundamentals for the later development of specific, safe, orally-effective drug therapies, ie, PDE-5 inhibitors. PDE Inhibition and Smooth Muscle Relaxation Phosphodiesterase (PDE) is an enzyme that causes breakdown of cyclic GMP, which is the direct intracellular mediator in the nitric oxide (nonadrenergic, noncholinergic) pathway. Discovery of this pathway led to a Nobel Prize in 1998 for the scientists responsible. The nitric oxide system causes relaxation of smooth muscle in blood vessel walls, ie, vasodilation, in various organ systems. The direct intracellular mediator of the nitric oxide pathway is cGMP. PDE catalyzes the degradation of cGMP. This pathway is active in numerous organ systems, and as of this writing, a number of different PDEs are known. The various PDEs differ in their physiologic roles and tissue distribution. Type 5 PDE is concentrated in the penile smooth muscle of the corpus cavernosum, where its nor![]() |
Order cialisMal function is to inhibit erection by degradation of cGMP, the mediator of erection. Viagra and the new drugs Cialis and Levitra all inhibit PDE-5, which is an inhibitor for corporal smooth muscle relaxation, resulting in increased blood flow in the penis in response to sexual stimulation. Comparison of Viagra, Cialis, & Levitra No head-to-head trial comparing the 3 PDE inhibitors has been performed. However, some differences between the 3 are basic: a table has been created to illustrate the major differences. An obvious proviso is that extensive data are available on Viagra (more than 20 million men treated, more than 1100 peer-reviewed articles as of Feb. & 8217;03), but only limited data on Cialis and Levitra. Drs. Gresser and Gleiter from the U. Tubingen in Germany have compared the three drugs via literature review (Eur. J. Med. Res. 7:435, 2002) In brief, efficacy is approximately 70% with all 3 drugs. The side effect profile is similar among the 3 drugs, except that blue d![]() |
